Hi Guys........ time to check in
Im working hard this week getting my FJR customers headers done, and on the way. Looking and talking on forums has to come when I can see some daylight or still have enough energy to post.
So I have a few minutes now before I start my 2nd shift at Cycle imports help building a 1216 Bandit motor tonight.
Ok heres the deal on my FJR Holeshot 4-2 header system
1. First came out with a set of nice slip-ons.
2. Worked over the last year on my new header design, yes i own a dyno and put many, many pulls on the FJR. But for now you will not see any charts here or on my web page when I get it up in a week or two.
WHY you ask ??????
Because my original bike had low miles when i developed my slip-ons. Marcs bike had much higher mileage and all the mapping work was done on a different dyno, not mine.It reads about 3 to 4 hp less than mine does. This is at my buddy Richards shop, Cycle Imports. He and I work tegether alot and he installs my customers parts here locally.
I can tell you there is about a 6 to 9 hp gain, with good mid range as well from stock, to all done with the full system and my map.
If I get a low mileage new bike in I will start from stock and have before and after dyno charts at that time. Those will go on my web page then.
3. Was not going after a big power gain with this pipe, did not want to kill the mid range , wanted to make a few hp if possible and make much less heat. Much less heat is what Im hoping for and im sure I have that handles pretty well.
Like mentioned my header is only about 1/8th ID larger.......on purpose.
I ceramic coat my headers inside and out, and that really holds the heat in. Marcs pre production header was not coated at all and he noticed less heat on his legs and feet !
They run real cool coated in and out !
Those stock cats have to radiate heat up to the rider
4. Tested a cross over and it did not help much, and all it would have done is drive the cost up to produce the pipe.
5.My header is lighter but to be honest i did not weight the stock unit to see exactly how much.
6. As far as EPA goes, hey my stuff is for closed course racing purposes only......HA!
7. I made this system so my current slip-on customer can up-grade at a later date.....nice option.
8. Have decided others can also buy the header onlyas well, and it will fit with any brand X slip-ons or even the original factory mufflers.
9. Have a custom map that I worked on over a month with Richard at Cycle Imports on Marcs bike, thanks dude for the use of your FJ
You will get the map free from me once you buy the header , but note this map is for the full system with my slip-ons. Other slip-ons and the header should be fine with this map as we well.
I may do another map someday with the stock mufflers and the header if i get a bike in here with that combo.
Im tired and have a few hours to go, so got to run now.
I will check back in but if you have any questions please call me at my shop.
If its ok to post prices on here let me know, and I will do so for all the options
Sorry for any typos !
Cheers Dale
